The concentrations of N, P, K and S in Mungbean stover and seed as influenced by potassium and sulphur application

Abstract

A field experiment was conducted at the Sher-e-Bangla Agricultural University Farm, Dhaka 1207 during the kharif season of 2014 to study the growth and yield of Mungbean (BARI Mung-6) as influenced by potassium and sulphur. The experimental soil was silty clay loam in texture having pH 6.14 and organic carbon content is 0.68%. Four levels of potassium (K) (0, 15, 25 and 35 kg K/ha) and three levels of sulphur (S) (0, 3 and 6 kg S/ha) were used in the study. The results reveald that grain and stover yield of mungbean increased with accumulation levels of potassium and sulphur. The N, P, K and S concentration of mungbean increased significantly from control to K₂S₂ (25 kg K/ha + 6 kg S/ha) and again decreased with increasing potassium more than 25 kg K/ha. Application of potassium and sulphur fertilizers increased organic carbon, derived from N, P, K and S status of postharvest soil significantly.
